APES Ecosystems & Biodiversity Unit Study Guide



After completing the Ecosystems & Biodiversity Unit, you should be able to…Identify major components of an ecosystem:Biotic and abiotic factorsProducers and consumersHerbivores, carnivores, omnivores, detrivores, and decomposers.Explain the processes by which organisms attain and convert energy:Autotrophs, heterotrophs, chemotrophsPhotosynthesis and cellular respiration (aerobic and anaerobic)Illustrate and explain how energy is transferred throughout an ecosystem:Food chains, food webs, and ecological (energy) pyramidsDiagram and explain how matter is conserved in biogeochemical (nutrient) cycles:Hydrologic, carbon, nitrogen, phosphorous, and sulfur cyclesUse a carbon budget to identify carbon sources and sinks, calculate fluxes between reservoirs, and support claims on how human activities affect the global carbon cycle.Describe the process of evolution by natural selection, provide examples of this process, and explain phenomenon that lead to natural selection.Mutations, adaptation, geologic processes, environmental conditionsExplain the processes that lead to speciation and extinction and the role human activities play in both phenomena.Identify, provide examples of and describe the importance of roles that species play (niches) within an ecosystem:Native, non-native, indicator, keystone, and foundation speciesIdentify, describe, provide examples of species interactions:Interspecific competition, intraspecific competition, predation, parasitism, mutualism, commensalism.Explain factors that can limit a species population size:Range of tolerance, limiting factorsDescribe how communities and ecosystems respond to changing environmental conditions:Ecological succession and sustainabilityDescribe solutions to endangerment and extinction of species:Laws, prevention, organizations, treaties, protected areas_____________________________________________________________________________________Chapter Readings & Review QuestionsChapter 3 Chapter 4 Chapter 5Chapter 9Review Questions pg 78, 4-9Critical Thinking pg 78, 2-8Eco Footprint Analysis pg 79, #1-3AP Review pg 79A/B, 1-13Review Questions pg 101, #1-9Eco Footprint Analysis pg 103, #1-3AP Review pg 103A/B, #1-13Review Questions pg 122-123, 2-5, 8Eco Footprint Analysis pg 124, 1-2AP Review 124A/B, 1-13Review Questions pg 214-215, 2-9Eco Footprint Analysis pg 216, 1-2AP Review pg 216A, 1-12_____________________________________________________________________________________________Key Terms: Ecology, biodiversity, species, population, ecosystem, community, biosphere, photosynthesis, cellular respiration, aerobic respiration, anaerobic respiration/fermentation, producers, consumers, herbivore, carnivore, omnivore, scavengers, detrivores, decomposers, autotrophs, chemosynthesis, biotic factors, abiotic factors, food chain, food web, hydrologic cycle, carbon cycle, nitrogen cycle, phosphorous cycle, sulfur cycle, nitrogen fixation, assimilation, nitrification, denitrification, transpiration, adaptation, natural selection, evolution, critical factor, tolerance limits, limiting factors, habitat, ecological niche, generalist species, specialist species, endemic species, competition, speciation, geographic isolation, behavioral isolation, Interspecific competition, predator-prey/predation, mimicry, camouflage, mutualism, commensalism, parasitism, symbiotic relationships/symbiosis, keystone species, native species, nonnative/invasive species, indicator species, foundation species, primary succession, secondary succession, extinction, mass extinction, endangered species, threatened species, extinct species, HIPPCO, habitat fragmentation, poaching, CITES, CBD, ESA,._____________________________________________________________________________________________Unit Calendar:Wed. 10/10/2012 (Matter in Ecosystems)Conservation of Matter in Ecosystems: Biogeochemical CyclesFriday 10/12/2012 (Matter in Ecosystems)FRQ Peer/Self Grading for Pop Dynamics TestContinue Conservation of Matter in Ecosystems: Biogeochemical CyclesMonday 10/15/2012 (Matter in Ecosystems)Conservation of Matter in Ecosystems: Biogeochemical Cycles DUENOTES: Slides 1-2, 13-17Carbon Budget WorksheetWednesday 10/17/2012 (Energy in Ecosystems)Carbon Budget Worksheet DUENOTES: Slides 3-12Energy Transfer in Ecosystems ActivityMonday 10/22/2012 (Evolution & Speciation)Energy Transfer in Ecosystems Activity DUENOTES: Slides 18-30Symbiosis Mini-ReportWednesday 10/24/2012 (Major Species Roles)Symbiosis Mini-Report DUE, Group PresentationsNOTES: Slides 31-35Species Mini-Report Friday 10/26/2012 (Properties & Changes of Ecosystems)Species Mini-Report DUE, Group PresentationsNOTES: Slides 36-43Ecological Succession WorksheetMonday 10/29/2012 (Species Extinction)NOTES: Remainder of the SlidesBiodiversity LabWednesday 10/31/2012 (Biodiversity)Biodiversity LabMonday, 11/5/2012Ecosystems & Biodiversity Unit Exam ................
